Dan Eggen writes a bit carelessly about sales of guns at gun shows in this story on a GAO report finding domestic abusers are able to get guns illegally because of faulty background checks.

So:

The study, which was requested by Rep. John Conyers Jr. (D-Mich.), is likely to play a role in the debate on Capitol Hill over proposals to conduct background checks at gun shows, an issue that hinges in part on how much time the FBI should be given to complete the task.

And:

Andrew Arulanandam, a spokesman for the National Rifle Association, said the group could not comment on the GAO report until it has had a chance to review it. The NRA has consistently opposed longer background check times and is fighting efforts to require background checks at gun shows.

What the NRA is fighting, for better or worse, is imposing new conditions and longer background checks for small-time private gun sales, whether at gun shows, in the classifieds, etc. Whether that's a good idea is one question, but focusing on the gun show is part of the Jane Brady package.
